Abstract
L'invention concerne un système et un procédé de découverte de la longueur d'onde maximale du spectre détecté par un spectromètre LSPR. Le procédé consiste à lire une image représentant le spectre réfléchi/absorbé, à utiliser un modèle mathématique du système de spectromètre LSPR pour estimer une courbe paramétrique représentant le spectre d'absorbance/réflectance, et à ajuster ou optimiser les paramètres de la courbe paramétrique de façon à augmenter la probabilité que la courbe paramétrique représente le spectre détecté. L'invention concerne également un nouveau procédé d'obtention d'une réduction du bruit de signal de longueur d'onde maximale LSPR à l'aide d'un algorithme de régularisation adaptatif.
